Gov. Andrew M. Cuomo and State Senator Jeffrey D. Klein both face
primaries on Tuesday in part because they have helped Republicans keep
power in the State Senate.

The
issue of party loyalty in the Senate has provided fodder for multiple
primary campaigns this year. Mr. Klein agreed in June to end his coalition
with the Republicans and reunite with his fellow Democrats after the
November elections, but some liberals remain skeptical about his pledge
and resent the formation of the coalition in the first place.
